Hi Eugen,

Thanks for writing your suggestion. 
On beforehand I would say that I do not agree with you. It's not for nothing that both are offered and work separate ..

You could start a discussion on the UX-list, if you like to see what others think.
Cheers,
Cor

Thank you for helping us make LibreOffice even better for everyone!


Warm Regards,
QA Team

Can reproduce on LibreOffice 4.2.4.2 (from OpenSUSE), setting to NEW.

I do agree with Eugen to some extent: the setting in Tools > Options > LibreOffice Calc > View should also toggle the setting in Format > Page > Sheet _on new documents_ (or documents where the Page setting is unset in the XML format).
That way both options could stay mostly independent and the general user expectation of printing what is on screen would be met. If a user wants the display & print options to differ, they would have to set that once per document.

One is in the VIEW settings and the other is in the TEMPLATE/document settings.
IMO this is a WONTFIX
Setting so in absence of any discussion on UX. 

Pls let's don't change old behaviour without very obvious reason or decent discussion :)

If you are aiming for discussion, I don't get why you would be closing the bug (which generally is an attempt to shut down further discussion)...
Not reopening solely to avoid an open/close-war, but I think this should be reopened.

Enough war without us adding some ;)
Will set to NEEDINFO then ..

because that is what we need from a proper discussion IMO

Per new procedures, moving this to NEW and requesting ux-advice (Stefan, et. all). This should not be in NEEDINFO - it's a simple UX enhancement request that UX should decide how to move forward.

Regina, is there any reason to hide zeros per workstation and not per document like it's done for printing?

(Added this topic to the agenda for the design meeting Nov/29 2017.)

The property ShowZeroValues is per document. The setting in Tools > Options works on the current active document. For new documents it is always checked, in case you use the default document template.

There is no ODF property for ShowZeroValues, but it is saved in the settings.xml. Content of the setting items in the settings.xml file are not standardized. So if LibreOffice decides to change the behavior so, that it is per sheet, that would be possible without ODF problems.

For printing it is standardized in ODF. It is the attribute style:print in the element <style:page-layout-properties>.

In the beginning it was not clear for me where to find these checkboxes so if somebody has the same problem then here is the precise location of them.

The Tools -> Options -> Libreoffice Calc -> View -> Display -> Zero values checkbox 
- is an application-wide setting and 
- determines whether the zeros are to be shown or hidden _on_the_screen_.
By contrast, the Format -> Page -> Sheet -> Print -> Zero values 
- is a setting with the scope of the current file and 
- refers to print or not to print zero values.
	
It is obvious that the current behaviour can be confusing if the printed content is different than the one on the screen. 
	
I personally cannot see the benefit of hiding all the zero values globally in all documents so I think the Tool -> ... -> Zero values is useless in its current shape, therefore, it should be removed.
	
On the other hand, the Format -> ... -> Zero values setting has its benefit but the location of this setting is not the best, nor the usability. 	
	
I think whether to display zero values or not, it should be a toggle switch under the View menu, for example: View -> Show Zero Values, similarly to the View -> Formatting Marks in Writer. The reason is that in most cases it is not a per-document setting. It is much rather a per-moment setting. I want to see the zeros _now_ and don't want to see them a minute later. This setting should not be saved into the document but its current value should impact both the screen and the printed versions.

If the user wants to have _saved_ settings for hiding/showing zero values then they should use conditional formatting on the appropriate cells (or all of the cells). Format -> Conditional formatting -> Condition -> "Cell value is equal to 0, Apply style -> Hidden". 
	
(The Hidden style should be defined at first with Apply Style -> New Style -> Organiser -> Name = "Hidden", Numbers -> Format Code = "")

We discussed the topic in the design meeting. The visualization option in tools > options is independent from the printing option under page > sheet, which could be improved by taking what is configured globally for newly created documents. But we expect to run into other trouble with this approach and concluded to accept the current behavior.

Btw, meanwhile cell styles and conditional formatting has improved significantly. Hiding zeros by white font color could be a good workaround.

Conditional formatting style with white font is overkill (i.e. quite heavy if used a lot) in most situations and doesn't help when changing the cell background. Consider using a number format to suppress displaying and printing of 0 values, for example

0.00;-0.00;;

Note the empty code in the third (=0) condition.
